. The invention relates to wheel stopsi'o f the 'typeadapted to beapplied to carralls at various points to engage a car wheel and preventmovement of the car along the track irrespective of the functioning ofthe car handbrake. The-main objectof the present invention is to providea simple,.economical effective stop'easily applied to and removedzfromthe I rail without drilling or other. work on the rail and, preferably,to provide a wheel stop which ,will I automatically tighten itself tothe-rail irrespective. of. careful applicatlon by'the user andirrespectiveof wearer other conditions which might tend temporarily toloosen the device; I 1 v In the accompanying drawings 1llustratring theinvention Figure 1 is a side elevation of asimple lformof stop showingthe trafiic rail to which it is applied and a car wheel engaged by th p'l I 0 1 Figure2 is .a transverse vertlcal sect on on the line '2--2 ofFigure 1. p

' The traflic raill is shown "mounted on cross ties 2in the usualmanner. .Thestop device. includes a block-like body 3 having a groovedunderface 4 arranged to rest upon the rail substantially throughout thelength of the device, .Bloclr3 has a forwardly fac- 'ing'wheel engagingsurface 5 preferably pro- 'vided with the same contour as the wheel 6.The rear portion of body 3 tapers. downwardly andrearwardly from thewheel engaging portion and includes an upwardly facing surface 7. Aloopmember encircles the rail and the rear portion of the body of thedeviceand comprises a U-shapedstrap 8iand a transverse, key 9v extendingthrough suitable openings provided therefor in the upper portions of thelegs of the strap 8.

of the block along the rail. The lower portion 'of strap 8 will abutagainst the forward face of one ofthe cross ties ifthe'frictionalj'resistanceto the movementof the blolck is insulficientto lock the same to the ra1 l The'form shown in Figures 3 and 4 includesa similar stop block l2and a downwardly opening inverted U-shaped member13 of round rod having eyes15 formed in the lowerends ofits legs forreceiving. a holding pin 14. a The tapered surface 16 of the blockcorresponds. to .surface 7 in'Figure .1 and acts as a wedge to tightentheassembly of the device with the rail as Wheel pressure is applied tothe block.

v Figures 5 and 6 illustratea. structurein which the block. body 17 hasa longitudinal groove 18 in its inclined upper face and the sides ofthis groove are perforated at intervals as indicated at 19,. A separatelug 20 the block by a pin 21 passing through opentioned by lug I v Thisconstruction adapts the device for application to rails of differentheights and si'zes the full line showingof lug 20 and loop member 22indicating the application to a relatively high rail and thedotted lineshowmay be positioned at various points along" gaging element having arearwardly and -downwardly inclined wedge-like portion constructed to,overlie the rail, anda' loop member 'arranged'to encircle the rail andsaidportion. i

the lower face of the wedge-shaped key 27 passing through the sides ofthe strap 28.

This notch and key construction also adapts.

the device for application to rails of different heights. 1 y In Figure11, the body 29 has an upstanding rear wall 30 threaded to receive thescrew 31 which. extends longitudinally of the block. A loop. member 32encirclesthe rail and the lower portion of'block29, passing through aninclined groove 33 in the block. Theinner end of screw 31 is providedwith a seat 34 forthe upper'cross bar 35 of the loop member and byrotating screw 31 the device may beadjusted tofitrail sections ofvariousSIZQS.

Each ofthe structures illustrates a wheel engaging block having. awedge-like body extending lengthwise of the rail'and pro.-

vid'edwith a simple loopfor holdingthe device to the railandanymovement; of the body along the rail under the thrust of the wheelwill serve to increase the resistance" of the device to. such movement:

Various other forms ofth e invention may be made withoutdepartingfrom"the spirit thereofand the exclusive use of modifieddetails of the construction coming "withinthe "scope ofthe claims iscontemplated.

What is claimedv is: 1. A wheel stop consisting'of' a wheel en- 2. Awheel stop consisting of a wheel engaging element having" a rearwardlyand downwardly inclined wedge-like portion constucted to overlie therail, and a loop memberarranged to encircle the rail and said portion,said loop member including a Wedgelikeelement extending transversely ofthe device and'movable through said member to reduce its effectivelength. 7

3. In a wheel stop, ablock arranged to lie upon the. top ofa rail withits forward end disposed to engage a car wheel and with'its top faceinclined downwardly and'rearwardly from said forward end, and a linkmember overlying said top face and constructed to underlie the rail,whereby said block will be clamped to the. rail as it is movedrearwardly relative to'said member.

' 4:; A wheelstop compri'singa block constructed to lie upon a car railand to project upwardly therefrom to engage a car wheel and having a topface inclined downwardly and rearwardly from its wheel engaging face, aU-shaped member constructed to receive said block and the rail betweenits legs, and a removable pin extending between-the outer ends of thelegs of said U-shaped member.

-5. A wheel stop comprising a wedgedike block with its undersidechanneled to receive the head of a rail, a Ush'aped member applicable tosaid block and the rail upon which it rests, and a transverse wedge-likeelement extending through the-router portions of the legs of saidmember.

6. A'wheel stop comprising a wheel engaging block constructed to-rest-ontop ofa car rail and having a portion inclined downwardly and'rearwardlyfrom the wheel engaging face, a loop member forencircl-ing said "i blockportion and the rail upon which it rests, and means for holding saidloop member in position on said block.

7 A'wh'eel stop comprising a wheel engaging block'constructed torest-ontop of acar rail and having a portion inclined down wardly andrearwardly fromthe wheel engaging face, a loop member for encirclingsaid blockportion and; the rail upon which it rests, and means forholding said loop memher in different positions alongsaid inclinedportion. r

8. A wheel stop comprising a-wheel engagingblock constructed to rest'ontop ofa-car rail and'having a portion inclined downwardly and rearwardlyfrom the wheel-err gaging face, a loop member for encircling said blockportion andthera'il uponwhich it rests, and means for holding said loopmem- 7 her in different'positions alongsaid inclined portion, said means.compris'inga pluralityof notchestraversing said portion and adapted toreceive the upper cross bar :of said loo p member. I

9. A wheel stop comprising a wheel engaging block constructed to rest.on top of'a car rail and'having a portion inclinedfdownwardly andrearwardly fromthe wheel engaging face, a loop member for'encirclin'gsaid block 7 portion and the rail upon .whichit rests,.an-d

means for holding saidloop member in difierent positions along saidinclined portion, said means comprising an element bearingagainstthe'rear faceof th'etop cross bar of said loop member and a deviceforpositively moving said element forwardly alongsaid portion.

10. A wheel stop comprising a wheel engaging block constructed torestontop of a its car rail and havinga portion inclined downwardly andrearwardly from the wheel engaging, face, a loop member for encirclingsaid'biock portion and the rail upon which it rests, and means forholding said loop member indifferent positions along said inclinedportion, sald means comprising'a screw threaded into a part of saidblock and extending longitudinally of said inclined portion and engagingthe rear face of the upper cross bar of said 100}; member.
